LOCKING DEVICE FOR DEMOUNTABLE WHEELS.

Specification of Letters Patent.

Patented July 23, 1918.

Application filed April 11, 191,7. Serial No. 161,149.

To all whom t may concern.'

lie it; known that l. (lIJmHcNr Boo'rn, n citizen of the United States, residui#r at Nnrberth, Montgomery rountxv, Pennsylvanin, have invented an Improved boeking Device for Demountabln ll'heelxw oi' whirh the following' is a epeeitieation.

My invention compi-inw improved lot-king mechanism of simple and etiieient rharaete-r designed primarily for holding in operative poition the demonnt'ahie members ot wire wheels, and itis embodied in a mit adapted for holding); the parts of tin` huh in operat ire relation and a device for xing' `aid nut in place, the preferred form oi" the invention comprising a nut having coneentrie parte,v provided with thread@` and a` uut adapted to screw into the onteipart and into edging engagement with the yinnler part; lor the pur poseof fixing it on the part with which it is engaged.

The characteristic features oi' my inven tion are more fully set outy in the following description and the :n'eoxnpanying4 drawings, in which4 Figure l is a part eeetional elevation of a Wheel having my invention applied thereto; Fig. 2 is a sectional view on the line of Fig. l; Fig. 3 iS a `Qectional View on the line 3-3 of Fig, 1; and Fig. at is. an end view ofthe hub, including its cap and lot-ltingr device.

As Shown in the drawings, the driving shaft. l han eplined thereon the hnh body 2 provided with a tapered Section 2, a hexagonal section 2" and a eylimlriezd threaded art; 2, the body being Secured on the Aallait liy n nnt 3 Within the recess 2 in the outer part of the body.

A shell and outer hub section 4 is; sleeved on the body 2 und has a tapered section 4 fitting closely on the section 2a. V A. second, preferably hea vier, Lhell and outer hub Seetion 5 is Slved on the body J and has the hexagonulfseetion 5 engaged on the hexagonal section 2b, the section 5b teleeeoped within the outer end 4b of the shell in the Sironi der 5 nbutting against `the end 4'), and the outer section 5 surrounding the threaded section 2c.

Inner .spokes t5 and outer epokes 7 respeetively eonnoet the inner part 4 of the shell l and the outer part. 5 of theshell 5 with the wheel rim 8 havin ,the tie 9 thereon.

The deniountnble wlieel is loeL d inplaree by u compound not comprising the cylindriral. body 10 adapted to pass within the part h the Hanne 1t)a extending outwardly from the hod for engagement with the outei end ol the parte fi", and the 4werlions. 1U" turned inwardly trom the bodyl to eonrenlrie relation therewith. the sections IU" being sepa rated b v the *Iota lll" and havingY threads It)Il t'or engagingF the threaded iwellen LJ".

not l im provided with an external thread lt.rx l'or engaging' the internal thread 1U on the outer ringr or bedr ttl and an internal eonit-:il urtare li" hu' engnging the external ronit'al eul'l'aw it!" of the inner Split, ritruj formed by the #t-etiouh ltt" l'or etlertiugr a wedgiun' notion to ,spring the latter in wardly into tirlniv rdrippingI4 relation to the Vpart 1",tiie nut l1 having.;r a hexagonal :iovket Il" for the engagement ot' n wrenrh.

VThe foregoing: methtininm eomprizwes few' und simple parte` rrndilv produced and operated and :ltl'orthy :in etlieieni and Secure loch.

The demolnitable wheel, when mounted on the hub body` drivenl through the interioriting hexagonal set-tion i and fi". the seetion il being` held in pince and holding' the `eertion 4 in. place simply and sernrelyhy lezerewing the resilient nutsertione` ttt" on the station and the ont il into the nut bothr 1t) eo as to presl the parts ttl" againsty the part 2.

Having described my invention. l claim:

L The, combination with liXed and de mountable hub eeetious, oi a nut having z, part engaging one ot' Suid hertiou,`v and a part withering;` the other ol' said Settions to hold them together` and a wedging device aetingj between eaid parts for looking said nut.

2. The combination with Iixedand demount-able hnh sections, of a deviee eompris ingr eoneentrie memberl tor securing said soutiens together, the inner of mid members being: divided and threaded to engage :i threaded portion of one of Said sections and the outer of said members engaging the other of said seetions. and a. device having a wedging' engagement with Said inner inember and a threaded engagement with said outer member.

The combination with :L hub body und a shell sleeved thereon, of a nut comprising an inner threaded split rinlg adapted to be screwed on said body and an outer threaded ring` having a liange adapted for engaging said shell, said split ring having n bevel, and a nut having a thread adapted for en geging the thread of Suid outer ring and e bevel adapted 'for engaging Said bevel firs-1 named to clump seid. split ring to seid hnb body.

4. The combination. of fin inner men'lber7 :1n outer member, e device havingr inner and outer parte adapted for engaging seid inner and outer members respectively, :md n Second device adapted for making e positive engagementJ with one of Seid parte and n Wedging engagement With the other of seid parts for locking said device first muned.

5. The combination of :in inner member, an outer member, n nut having n body provided with e flange adapted for engaging said outer member and e conical perl within seid body adapted for engaging Seid inner Lamaze member, end n nnL adapted for engaging! Hnd body :ind havingr :i conical purl, adapted i for engnging Seid conical part firs'ty named. The eombimlliion of en inner threaded pnrti, :Ln outer pnit hnvixngr :in inierleckiing1 engugemem with Suid innerpnrt, :l nut pre vided with nn internnlly threaded body l'mvY ingr :in outwardly extending' flange adapted for engaging said` outer member end in turned resilient, threaded parts adapted for engaging said inner pnlt, und n nut adapted for pressing' Huid resilient, part against; said inner )mrt :ind havingr :in external thread adapted for engaging seid threaded body.
